摘要：

In November 2010, the search for the He-4-eta bound state was performed with high statistics and high acceptance with the WASA-at-COSY facility using a ramped beam technique. The signature of eta -mesic nuclei is searched for in the measured excitation functions for the two reaction channels: dd -> (3)Hen pi(0) and dd -> (3)Hep pi-near the. production threshold. This report includes the description of the experimental method and the status of the data analysis.
